Who is responsible for maintaining the chain of custody for evidence?

• A. Anyone who handles the evidence must document its transfer.
• B. Only the investigator.
• C. Only the prosecutor.
• D. Only the court.

Answer: (A)

Maintaining the chain of custody means keeping a documented, traceable record of every transfer, handling, and location of the evidence from the moment it’s collected until it’s disposed of or used in court. The best answer is that anyone who handles the evidence must document its transfer. This ensures a clear, auditable path showing who had the item, when, where it moved, and for what reason, which helps protect the evidence from tampering, contamination, or questions about authenticity.

In practice, this covers all stages: from scene collection and packaging to transport, storage, analysis, and courtroom presentation. Because evidence often passes through multiple hands—a patrol officer, a crime scene technician, a forensic analyst, a supervisor, and potentially an attorney or court official—only requiring documentation by one role would create gaps. The requirement that every handler documents transfers preserves integrity and supports admissibility in court.

Choosing roles that restrict custody to a single person (like only the investigator, only the prosecutor, or only the court) would fail to account for the practical movements and processing the evidence undergoes, leaving the chain vulnerable to gaps.
